the 8 in 8,420 is 10 times greater than the 8 in 6,870

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

y/x of point b= y/x of point a
